Abstract: 827,777. Removing articles from moulding presses. BRITISH INDUSTRIAL PLASTICS Ltd. April 23, 1958 [April 26, 1957], No. 13444/57. Class 87(2). Moulded articles are removed from a moulding press of the flat bed type by a power operated stripping plate movable into the press "daylight ". Once in every cycle of operation of a press having platens 1 and 2, two reciprocable stripping plates 11 cooperate with upper and lower moulds 3 and 4, and collect the moulded articles from the ejector pins 6 and 8 of cavities 5 and dies 7 ; said plates being slotted at 13 to avoid. said pins. The drive of the plates 11 is provided by horizontally disposed hydraulically operated jacks 17, each having a piston 16 of such length that a rack 14 attached thereto turns a lever 25 by means of a pinion 20 through about 180 degrees at each stroke. Each lever 25 has pivotally mounted thereon a block 26 slidably mounted in the grooves 27 of a guide member 28 which is connected to the plate 11 by a bush 29 slidable on a rod 30 which ensures that the plate moves linearly with respect to the press. The length of each lever 25 is half the distance travelled by the plate 11 into the press. Each stripping plate and drive mechanism is supported on a cross beam 19 which is connected to vertical supports 44 which are rotatable so as to vary the height of the plate 11 with respect to the press.

Abstract: 1,188,972. Extruding. DAVY & UNITED ENG. CO. Ltd. 20 March, 1968 [23 March, 1967], No. 13677/67. Heading B3P. An extrusion press has a platen 3 disposed downstream of the single billet container 4 into which billets 20 are loaded through a cavity 9 in the platen. The cavity houses a transverse slide 10 for the die carrier 11 and intermediate bolster 12 and another transverse slide 13 for the back bolster 14. The slides are moved by separate cylinders 15 and have a hole or preferably a U-shaped channel 18 for receiving a hot billet 20 and possibly a dummy block 7 from a tray 21 extending from a furnace. The slides 10, 13 are then moved transversely to align the billet with the container bore into which it is pushed by a cylinder 23 carried by the slide 13. During extrusion of the billet by press stem 6 and dummy block 7, the extruded product passes into a guide tube 26. After extrusion, the slide 13 or both slides are moved transversely to shear off the discard. Alternatively a separate shear may be provided to move across the rear face of the die after withdrawal of the container. Platen 3 is connected to four tie rods 2 of square section. Container 4 is movable axially by cylinders (5), Fig. 1 (not shown), to facilitate removal of the discard and dummy block. The slide 10 may be replaced by a rotary member.

Title: Improvements in or relating to the production of reinforced plastic tube
Inventor: BANE ARTHUR
IPC: B29C48/05
Filed: 1953-05-18
Abstract: 747,732. Synthetic resin tubes. POLYCHEMICAL DEVELOPMENTS, Ltd. May 10, 1954 [May 18, 1953], No. 13829/53. Class 99(2). A tube of plastic material, e.g. polyvinyl chloride or cellulose acetate butyrate plastic known as Tenite II Grade 435E, has an intermediate reinforcing layer 2 including at least a proportion of composite threads having a core of wire onto which textile yarns are bound or gripped. Preferably, the threads comprise cotton, rayon or nylon yarns twisted in one direction around a core of high-tensile steel wires, one or more wires being twisted over the yarns in the opposite direction to bind the yarns to the core wires, and the outer wire or wires being spaced well apart so that the yarns are gripped and seized against the core wires at intervals whilst being exposed for bonding to the plastic material between the convolutions of the outer wire or wires. The wires may be preformed before coating with a plastic material the same as or different from that employed for the wall of the tube. As shown in Fig. 1, a composite thread is wound into helical grooves 3 cut in a tube 1, and an outer cover 4 is extruded over the threads ; alternatively, a thread is wound into each of a number of parallel grooves. In a modification, Fig. 2 (not shown), the reinforcing layer is braided around the inner tube 1. The reinforcement may comprise a tubular fabric base produced by weaving, braiding, plaiting or knitting, or a flat fabric placed around a former and stitched or otherwise secured along the seam, such reinforcements being mounted on an expansible mandrel and a synthetic resin being applied thereto by rollers and calendered in position ; alternatively, the resin is applied by jets or sprays, the rollers serving to force, the resin into the reinforcement by pressure. Where heat treatment of the resin is required this is effected by the use of a heated pressure roller. If a flexible tube is required the plasticized resin is used and is applied in a partially cured or partially polymerized form and converted to its final state after the impregnation or application of the tubular base. Specifications 712,047 and 747,726, [both in Group VIII], are referred to.

Abstract: 711,223. Feeding and delivering sheets. MILLER-LAUFFER PRINTING EQUIPMENT CORPORATION. June 11, 1951, No. 13841/51. Class 100 (1) Sheet separators and carriers.-An apparatus for feeding envelopes comprises two endless chains travelling in unison along substantially parallel paths, pairs of laterally aligned fingers secured to the chains, a feed belt having a substantially horizontal portion supporting a stack of envelopes standing on edge with their flap folds uppermost so as to deliver the envelopes successively to a position between the chains, such that the fingers, while moving upwardly, engage the fold at each end of the envelope flap to remove the envelopes from the belt, and means to drive the belt in timed relation with the chains. A preferably rubberized belt 7 frictionally engages the bottom edges of substantially vertical envelopes to feed them towards a slanting abutment 10 which tilts the envelopes forwardly, such that air from a pipe 12 may blow the flap of the foremost envelope apart from the envelope body to permit a pair of laterally aligned fingers 21 to engage the flap fold of that envelope. The fingers 21 are carried by a pair of chains 17 driven by sprockets 14, the fingers being of thin flat strip metal projecting in the direction of travel of the chains ; alternatively, the fingers could be replaced by small pins projecting inwardly of the chains. A plurality of friction drags 35, comprising thin-gauge metal strips engage the envelopes to settle them firmly on the fingers 21. The chains 17 carry the envelopes to a cylinder 4 carrying type plates around the peripheral margins of the cylinder, the spacing of the plates corresponding to that of the fingers 21 along each chain 17. Delivery apparatus.-After printing, the envelopes are accelerated by preferably rubberized belts 38, Fig. 1, moving at a higher speed than the chains 17, such that the envelopes are disengaged from the fingers 21 ; rollers 41 resting on the envelopes increase the friction between the belts 38 and envelopes. A guide bar 42. guides envelopes leaving the end of the belts 38 downwardly on to conveyer belts 43 which move the envelopes towards inclined abutments 49 against which they are stacked.
